Title: Matt H 11/11 Commit

Recoded most of the variables that are supposed to be discrete as factors. Investigation of certain certain cigarette variables that are supposed to be coded with discrete ordinal values that appear continuous. From the Codebook, if the respondent answered 16 of the 17 questions the missing value was imputed using a weighted least squared regression. The nicotine dependence variable, NDSSANSP, should be an continuous variable due to that regression imputation while the ordinal variables may have to be rounded up/down.

I'm open for discussing that particular data quality/integrity question, since it will impact how EDA is performed.
